Gas Laws & upcoming

For Gas Law problems, Rule #1 - ALL TEMPERATURES MUST BE IN KELVIN

Click this link for the problem sheet and an answer key.

We will have a quarter test on November 8, 2017. This test will include all materials since the beginning of the year. There will be review sheets passed out in lab sections on Thursday and Friday. Please make sure that you know this material.

These are links to videos about the topics that we will be covering in this unit.

Three States of Matter

 Phase Change

 Phase Diagrams

 Boiling Point

 Vapor Pressure

 Gases

 Avogadro's Principle

 Dalton's Law

 Graham's Law

 Boyle's Law

 Charles Law

 Gay Lussac's Law

 Combined Gas Law

 Ideal Gas Law

 Mole

Environmental Science will have a quiz on Thursday. This is the FAQ sheet about the topic, and this is the notes of the PowerPoint presentation of the material that was shown in class.



In chemistry we have started a new unit. This is the link to the PowerPoint notes.

There is a chemistry test on Tuesday. There is a Castle Learning makeup posted. You will have until Tuesday Oct. 31, 2017 at midnight to complete. Go to Castle Learning and log into your account and take the Matter and Energy retest.If you score 85% or above I will average the retest and your original grade, if it raises your grade. If you score below
an 85% your grade will not be changed.

Review work

Many students missed Chem on Friday, due to a field trip. I was asked to post the review material that we did in class. Here are audio files of review for heat calculations and heating curves. Please refer to this heating curve or a similar one during that review.

We will have a unit test on Tuesday, Oct 24.

Testing

There is a one time reprieve for the PT test makeup. This will be posted today on Castle learning and students will have until Saturday at noon to complete. Same deal as last time: score an 85% or above and I will average it with your test score and change your grade. In order to benefit you must get a score of 85%, score below that and it will not change your grade. The test is called PT Makeup Revisited.



How to prepare for a test
Go through the notes and look at the terms that were used. For this unit these terms are:
Density
Standard temperature
Entropy
Endothermic & Exothermic
Conservation of Matter
Conservation of Energy
Kinetic & Potential energy
Formula unit & Empirical formulas
Balancing simple equations
Celsius & Kelvin
Phase
Boiling, Melting, Condensation, crystallization, Sublimation, deposition, fusing
Heating curve
Vapor pressure
Table H
Dynamic equilibrium
Specific heat
Allotropes

Make sure you understand these terms and you should do well.  The Test will be next Tuesday and will be 40 questions in the same format as the Regents test. Do well on the test and you will not have to do the makeup.

Table H

The worksheets from class can be found at this link. This is a link to a workbook on all the reference tables. Table H starts on page 31 and there is an answer key to the set 1 questions. This is a link to the set 2 questions key.

Balancing Equations & Invasive Species

In Environmental Science we are working on a project about invasive species. Students will prepare a presentation and show to class, beginning Thursday, 10/12. The presentation should include 6 organisms. The starting point is 3 animals and 3 plants, but fungi, bacteria or protists could be substituted for the other organisms. In class we were given worksheets, as a place to start for the information. All students will fill out brief evaluations of each fellow student and these will be considered in giving the final grade for this project.

In chemistry we are going through the notes on Matter and Energy, which can be downloaded here. We got to a worksheet on Accounting for Atoms, to help learn how to balance equations. Download Accounting for Atoms here.


There are many great videos on the Internet about the chemistry that we are learning. Here is a list of some that you may find helpful. Just click on the links.

Chemistry Test Periodic Table

We took the first unit test today. I should have it graded and the grades on the portal by Tuesday evening. There is a makeup test posted on http://www.castlelearning.com/ . Log into your account and take the test. You may take all the time you need, but the test must be completed by Monday night, 10/9/2017, by midnight. To raise your grade you must score an 85% or above. If you score >85% I will average your original grade with your makeup grade. The makeup cannot lower your test grade.

If you have any problems you must come to me as soon as possible. NO TIME EXTENSIONS will be granted for any reason!

Matter & Energy

We have a test on Tuesday. See previous entries to get the notes. This is a link to the study guide that was handed out in class for this test.
